That means Xbox One and Xbox 360’s “Jamais Vu” mission will be available on PlayStation 4 and PlayStation 3. And PlayStation 4 and PlayStation 3’s “Deja Vu” mission will be available on Xbox One and Xbox 360.

Jamais Vu puts players in the role of Raiden, who is investigating the Cuban island after reports of “Body Snatchers” reach the MSF leadership. And Deja Vu puts players in the role of a pixelated classic Snake, and recreates seven key scenes from the original Metal Gear Solid.

The missions will be available free of charge starting May 1 in Japan. A western date wasn’t announced, but we’d imagine it’s right around that time.
